IEUEL-CHARGING DEVICE FOR BRICKKILNS.

Application filed September 5, 1923. Serialj 1\T0@661',117.

zei1 of the Ge1n1an Republic. anal resident of Riecll ingen-on-the-Donau, \Vurtembei@ Germany. have i11\-enfe(l a new und useful1mprmed 1*uel-Clmrging Devim for Briokkilns, of wl1ich the following is a speeification. -Tl1e1e exist alreacly cl1arging clevices for brick-kilns in which the fuel .is conveyecl from tl1e coal receptacle into the kiln by means ofconveying Worms, stining blacles, drivers, 01 the like. The present invention is clistinguished from said'.known devjces by a rotary disk forming the boctorn of tl1e coal receptacle und being provicleclwith an opening tlnollgh whicl1 tl1e fuel is fecl into tl1e kill t-l1e fuel being uniformly clistributecl over tl1e area. of saicl disk or bottom ancl it being renderecl possible 130 let pass also comparatively large pieces of coal; besides, tl1e manner of operation is more reliable. 1

Tl1e rotatory botcom is proviclecl at its lower surfa e Witl1 a sloping cutvecl guicle plante extenclinp; from tl1e front eclge of the opening mentioned below it in rearwgTd direction, relatimly to the clirection 0f rotation of the. bottoml ancl terminating at sonne distance bel1incl tl1e rear eclge .of tl1e said. opening. The object of tl1is guicle plateis to prevent tl1e coal from falling eit her directly upon tl1e bottom of a casinglocatecl below it, 01, may be, direotly into the' Stoking neck of the kiln. Besicles the saicl curved plate, another ourved platte is attache'd to the lower surface of the rot-atory bottom, but tl1is other plate orwall is anr-- 1z1nged vertically ancl extends pa rtly along tl1e inne1 eclge of filme first-mentioned pla.te in horizontal .direction Wl1iCl1," however, changes aoc0rding to ehe curvature of sai cl inner eclge; vertically, the other ourved plate extends to the bottom of the casing. below it which contains the two plates in.

question, und tl1at part 01 half which is not in contact witl1 the inner eclge of the sloping guicle plate forms avertical Wall at some distance behincl tl1e remeclge ofthis plate, tl1at Wall forrnlng a verbical channel tl1roup;h wl1ich tl1e coal asses on its way down into tl1e kiln, The ve1ticalplate or Wall is of S-sl1ape, one part of tl1e S being in contacb with tl1e sloping guide platze. r.l1e other part forming the-vertical clmnnel.

The just-mentioned plate neecl not acmay be a little incl inecl so tlmt the channel mentioned .cof1es1)Ohdingly conioal ab that Wall formetl tl1e said plate; The inclinecl -part 0 l. tl1e Wall is preferably thafi opposlte the free edge 01 the sloping guicle plu te and tl1e direcaion 0f the inclination is such thal;

the Passage Cf the, coal "(hrough thelsaid channel is facilitatecl. v'Ihesloping gUide tiQlitening fing of angulz'zr seotion wl1i cl1 is affixecl to tl1e loWer rimof the fuel recepa tacle to which the rotatory bottom pertains,

plate is pref era bly shape cl simil'arto a part of tl1e thread of a screw. Another construc-f tional.memlaen of the device oo'nsists of a und the horizontal flarige of which is di 1ecteclinwarcls an'd ;xtends over the 1im of saicl bottom, as is all illu stratecl in the ac-" company1ng clraw1ng 111 wluch my 1nven t1on islllustratiad diagrammatically by way of exarnple. ancl in wl1icl1 Figure l is a verti cal section of tl1e chargi-ng -clev ice, Figur e 2 is a plan of.this device-; Figure3 is a s1de-v1ew ancl F1gur@4ya perspect1ve v1ew of the rotato-ry bottom, itssloping guide plante, and its ve-rtical-shapecl WllljFlg* ure 5 isalso=a vertioal secti-onthrough the entire chargingclevice tl1e Plane ofseiction.

into tl1e casing 4, and from tl1e eclgeof this opening exte1 1ds reamyards ancl downwards a sloping ancl curved guide-plat6 11, At; tl1e inner edge.ofthiplate ls a verti cal Wall 5 which is affixe'd t0 tl1e lower surface of tl1e bottom 1 andis S-shapecl, one half or part of the S being in*contaot with the inner eclge of tl1e guicle' plate ;ll, where3.s the other half o1 part extencls farther rearwarcls and fin ally plactically 1aclially '0i1miards, towarcls tl1e inner surface'of the. casing 4:. Tlns pa1t of the vertical wall whicl1 is locaecldpposite tl1e 1ear edge of the guide plate 11' forms a vertical clmnnel tln-ough whicl1 tl1 e coal passes when leaving the plate 11. This latterand tl1e Wall rotate, of.course'together With the bQQCQUJ l, and this being So,

the coal lying 011 the bottom of tl1e casing 4 is conveyed al0ng 0ver this bottorn in a circular path until it arrives ab the stokq neck 6 01 the brickkiln.

That pa1t 0f the wa1l 5 which is not in contact With the guide-plate 11 majy be a ]ittle inclined in Order to facilitate convey ing the coal into the neck 6.

This charging procedur is repeated. a1; every rotation 0i the bottoni 1 with its 1nembers 5 and 11, but the device may be modifiel in such a manner that continuous cha1ging is obtained. The only changes necessary to that efiect would consist in arranging the neck 6 in the centre part of ehe bottom of the casing 4., conducting t'he charging chann'el formed by the parts 5 arid 11 t0 that central neck, and rotating the bott0m 1 with its parts 5 and 11 from aboVe instead 0f The sloping guide plate 11 is prefembly s'haped like a par of a thread 0f a screw in order t0 obviate checking of the 00a] sliding down 0n and a1ong 0ve1 it.

The vertical shaft 10 i s supported by the bearing 6 and guided by the guide bearing 7. Both bearings a1e located be1ow the casing %L whereby they are prevented f1'0111 being af'fected Und, perhalns, destroyed by thc 00111 01' the heat, as is often times the c ase with the known charging devices f01' bricl ki1ns.
